“Some students have believed there was a "hidden data line" of tech in Scientology, a line on which Scientology tech was given out by me but not made known to students.

… There is no such line.

Thewhole of technology is released in HCO Bulletins and HCO Policy Letters and tapes I do and release.

I don't tell people anything in some private way, not even Instructors.

'… If it isn't written, it isn't true …' Somebody says 'Ron said to —' and on a veteran staff you hear the rejoinder 'Let's see it …' So we have learned the hard way — 'If it isn't written, it wasn't said'.”

“A 'hidden data line' is a pretense that certain data exists outside of HCOBs, books, and tapes.”
